Description

Part #: 32-2145

This 4-1/4" stroke 8-1/2" diameter flywheel assembly replaces the original flywheels in 1995-'98 EFI big twin engines. Timing notches on the rim of the left flywheel work with the stock crankshaft position sensor.

MIA's Description

Made of high-strength forged steel, this 4-1/4" stroke flywheel assembly is designed for stock and high-performance custom Harley-Davidson EFI Big Twin Evolution motor applications. It features a special keyed 6° large diameter tapered sprocket shaft for increased strength and uses standard S&S tapered crankpin and pinion shafts for ease of service. The 8-1/2" diameter assembly comes fully assembled, trued, and balanced for stock H-D 80" or 96" pistons, including the flywheel, crankpin, and connecting rods. Made in the U.S.A. for street riding.
